Expert Mould Testing & Remediation Services - Why Its Important 

  • Mould will grow where there is water and food available and is naturally present in the environment. It is nature’s decomposer. Humidity above 65% for more than 48 hours is sufficient for mould to start growing in your property.

  • Water damage may be the result of a building envelope or waterproofing failure, drainage issues, hidden leaks, or condensation. We will find the cause of your mould issues. (Research suggests 30-50% of properties in New Zealand are water damaged)

  • Around 25% of people have no immune response to mould and will experience allergy symptoms to common household moulds. Ongoing exposure can lead to serious health issues. Always seek a professional medical assessment to confirm if mould is a cause.  

  • Prolonged wetness caused by leaks can lead to toxic moulds developing in hidden places. These release invisible mycotoxins and volatile organic compounds that can cause serious health effects for occupants. Any presence of these types of moulds is of concern.

  • Mould spores are invisible and float in the air. Only comprehensive mould testing by professionals will reveal what fungal spores are present and the risk to occupant health.

  • Spraying mould with a mould killer can make it more toxic. Effective remediation requires first fixing the water problem and then removing the mould according to industry best practices. 

  • Mould must be safely removed by competent professionals. We work with the industry’s leading mould remediation contractors and can provide post-remediation testing to confirm remediation has been successful the dwelling is safe for reoccupation.

  • We can offer a low cost one-hour preliminary site investigation to tell you if you have a mould problem, what the cause is, and provide you with a health risk assessment of your dwelling.
